The present disclosure invents a catheter balloon that includes a membrane having a proximal end and a distal end. A plurality of substrates are bonded around the film. By using a reinforcement or stress relief, it is possible to increase the ability of the adhesive to withstand repeated stresses during use while also minimizing the overall thickness of the balloon near its distal end. The reinforcement can include a portion of the unassembled membrane. Alternatively, the reinforcement can include an adhesive edge tip. The stress relief can be a serpentine portion of the distal tail of the substrate. 本公开发明了一种导管球囊，该导管球囊包括具有近侧端部和远侧端部的膜。多个基底围绕该膜粘合。通过使用增强件或应力消除件能够提高粘合剂在使用过程中承受重复应力的能力，同时还能够使该球囊靠近其远侧端部的总体厚度最小化。该增强件能够包括未组装的膜的一部分。另选地，该增强件能够包括粘性边沿末端。该应力消除件能够是基底的远侧尾部的蛇形部分。
